Broderick, New Brighton, Staten Island, N. Y., assignor to Reynolds Metals Company, New York, N. Y., a corporation of Delaware Application September 9; 1937, Serial No. 163,142 7 Claims; (01. 229-16) The invention relates to a cake box.. The object of the present invention is to provide a strong, practical and attractive cake box of simple and comparatively inexpensive construction, which may be easily set up and arranged for use, and which after assembly is adapted to be collapsed to a flat condition for shipping or storing.

A further object of the invention is to provide a hexagonal cake box formed by die-cutting and die-scoring from a one piece blank and provided at diametrically two opposite sides with permanently connected parallel side walls and having at the other four sides interlocking wall-forming flaps and provided also with closure flaps hinged to and forming extensions of said permanently connected parallel side walls and foldable over and reinforcing the interlocking flaps and entirely concealing the same to present a smooth attractive appearance at the sides where the box may be opened to obtain access to its contents.

Another object of the invention is to provide simple, practical and eflicient frictional locking means for securing the closure flaps over the interlocking flaps adapted to enable the closure flaps to be readily secured in their closed position and capable of enabling the cake box to be readily opened without tearing or otherwise injuring the same.

With these and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appendedfit being understood that various changes in the form, proportion and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

Figure 1 is a perspective view of. a cake box constructed in accordance with this invention and shown arranged for use.

Figure 2 is a horizontal sectional view-of the same.

Figure 3 is a vertical sectional view on the line- 55 Figure 6 is a plan view of the die-cut and diescored one-piece blank from which the box is formed.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, l designates a die-cut and die-scored 5 one-piece blank constructed of cardboard or other suitable material, and preferably reinforced and ornamented with a layer of metal foil, but any other suitable material may, of. course, be employed in the construction of the blank. The 10 blank is die-scored at 2 to form a hexagonal bottom 3 which is connected at one side with a hexagonal top 4 by a side wall 5 formed integral with the top and bottom of the box. The top of the box is die-scored at 6 and the die-scoring 15 defining the hexagonal contour of the bottom and top 3 and 4 forms hinge joints or connections for hinging integral bottom and top interlocking flaps 1 and 8 to the bottom and top of the box.

The blank is provided at the side of the top 4 2o diametrically opposite the side wall 5 with an integral side wall 9 hinged to the topby the scoring 6 and extending from the top wall 4 and provided with an attaching flap l0 hinged to the side wall 9, the hinge connection being formed 25 by scoring II. The attaching flap I0 is securedby suitable adhesive or other means to the upper face of the bottom 3 at the side diametrically opposite the side wall 5 when the blank is assembled to form the box. In assembling the blank to form the box the side wall 5 is swung upwardly to a vertical position perpendicular to the bottom 3 and the top 4 is swung to a position over the bottom 3 in parallelism with the same and the side wall 9 is swung downwardly to a 35 position perpendicular to the bottom and top of the box. The attaching flap is then secured to the upper face of the bottom of the box. This provides parallel side walls at spaced points at diametrically opposite sides of the box. 40

The interlocking flaps I and 8 are connected to the sides of the top and bottom between the side walls of the box and each of the interlocking flaps is provided at one end with a cutaway portion l2 and has a substantially lobe-shaped tongue 13 located at the inner end of the cutaway portion and rigid with'the interlocking flap. The interlocking'fiaps of the bottom and top are reversely arranged and are adapted through their hinge connection with the top and bottom 3 and 4 to be swung into interlocking engagement in a vertical position, thereby forming walls for substantially closing the sides of the box between the walls 5 and 9 and confining the contents of the box within the same.

ally engage each other and also the contiguous ends of the interlocking flaps whereby the 010- The parallel side walls and 9 are provided at their ends with integral extensions forming closure flaps l4 and i5 and hinged to the side falls 5 and 9v by lines of scoring l6 and I1 and-provided at their outer ends with hinged extensions l8 and I9. The hinge Joints of the extensions I8 and I! are formed by scoring 20 and 2|.

The closure flaps are adapted to be folded over the interlocking flaps and the extensions II and is are insertable between the adjacent ends of the-pairs of interlocking flaps and they frictionsure flaps are securely retained in their closed position and at the same time are adapted to, be readily opened without tearing or otherwise injuring the box to obtain access to the contents thereof.

While the improvements are shown applied to a hexagonal cake box they are also applicable to other forms of polygonal boxes. The box may be ornamented in any desired manner and the top may be, as illustrated in the accompanying drawings, provided with openings 22 of segmental or other form for enabling the contents of the box to be .viewed by prospective purchasers. After the attaching flap III has been secured to the bottom of the box theblank is assembled and it may be shipped in the flat collapsed condition illustrated in Fig. 5 of the drawings and it is also adapted to be easily and quickly set up for use. When the closure flaps are folded over the interlocking flaps they reinforce the interlocking flaps and strengthen the box at the sides provided with the interlocking flaps and at the same time they completely cover and conceal the interlocking flaps and contribute to the production of a strong attractive box. The interlocking flaps stiflen the box when the outer closure flaps with their friction fitting marginal edges are in place overand covering and concealing the interlocking flaps.

What is claimed is:

1. A polygonal box including a polygonal top, a polygonal bottom, walls connecting the top and bottom of .the box at spaced points, interlocking wall-forming flaps arranged at the sides of the top and bottom between said walls and disposed in cooperating pairs, the members of each pair being provided with means for engaging each .pther, and closure flaps hinged to the ends of said blank by die-cutting and die-scoring and including a polygonal bottom, a polygonal top, an integral side wall connecting the top and bottom of the box at one side thereof, a side wall formed integral with the top and located at the opposite side of the box from the said side wall and provided with means for securing it to the bottom wall, interlocking flaps arranged in coacting pairs and extending from the bottom and top of the box at the sides thereof between said walls, the members of each pair of interlocking flaps being provided with means for engaging each other,

and closure flaps extending from the ends of the said walls and hinged to the same andfoldable over the interlocking flaps and having friction fitting portions insertable between the adjacent ends of the pairs of interlocking flaps.

3.

A hexagonal box comprising a hexagonal bottom, a hexagonal top, side walls connected with the top and bottom of the box at spaced points, interlocking flaps extending from the top and bottom of the box at the sides of the box between the said walls, and closure flaps extending from the saidwalls and foldable over the interlocking flaps.

5. A hexagonal box comprising a hexagonal bottom, a hexagonal top, side walls connected with the top and bottom of the box at spaced points, interlocking flaps extending from the top and bottom of the box at the sides of the box be-- tween the said walls, and closure flaps extending from the said walls and foldableover the interlocking flaps and being of sumcient sizeto cover and completely conceal the same. k
